Chemical and Physical Changes
a change in the form (size or shape) of an object
Physical Change
state of matter that keeps its shape and volume. Particles have low energy and vibrate slowly in place
Solid
state of matter that keeps its volume, but takes the shape of its container. Particles have medium energy and move freely at medium speeds
Liquid
the amount of matter or “stuff” that is found inside an object
Mass
a resource that can be replaced at the same rate at which it is consumed
Renewable Resource
a change in matter in which a new substance is formed.
Chemical Change
state of matter that takes the shape and volume of the container it’s in. Particles have high energy and move freely at high speeds.
Gas
change in state from liquid to solid
Freezing
the amount of space an object takes up
Volume
a resource that cannot be replaced at the same rate at which it is consumed
Non-Renewable Resource
a change in state of matter (ex: solid to liquid, liquid to gas, etc.)
Phase change
change in state from solid to liquid
Melting
change in physical state of matter from the gas phase to the liquid phase
Condensation
the measurement of how much mass of a substance is contained in a given volume
Density
materials or substances that occur in nature
Natural Resources
a physical change in which particles of a substance are separated by water particles
Dissolving
change in the physical state of matter from the liquid phase to the gas phase
Vaporization
vaporization of a liquid that occurs only on the surface of the liquid
Evaporation
anything that has mass and takes up space
materials made by humans that does not occur naturally on Earth
Synthetic
What day do we start school again in January?
January 8th

Sublimation
change in the physical state of matter from the gas phase to the solid phase without passing through the liquid phase
Deposition
